Reduced co-production of toluene and C.sub.9 and higher aromatics such as
trimethylbenzene, methylethylbenzene, and diethylbenzene is achieved in
processes for the isomerization of xylenes to close to equilibrium using
a layered catalyst having a thin outer layer of molecular sieve and
hydrogenation metal component on a core, wherein at least about 75 mass-%
of the hydrogenation metal component is in the outer layer.
